Silver Braze 54

SILVER BRAZE 54 TECHNICAL DATA

USES

Silver Braze 54 is employed in numerous furnace brazing situation because of its low zinc content. The US Air Force specifies it for many jet engineer sub-assemblies. It is used for making joints that are subjected to elevated temperatures, ranging up to 700F (370C) particularly on stainless steel.

BRAZING CHARACTERISTICS

Silver Braze 54 is an intermediate temperature silver brazing alloy with a rather long, 235F (130C) melting range. It has a tendency to liquate (Separation into low and high melting constituents) if heated slowly through its melting range. Therefore, it is preferable to use this alloy where the assembly can be heated rapidly to brazing temperature. The long melting range of this alloy is useful when wide gap joints are hand fed since semi-fluid alloys can be working across the gaps. Flux is recommended.

Rupture tests at 500F (260C) indicate that sound joints will stand a shear stress of 14,000 PSI for a period of about 650 hours. Tensile values of non-ferrous alloy butt joints will approximate very closesly the following results obtaned with other high silver-copper content brazing alloys:
